Dual Boot Windows and Ubuntu.

Let us Take 80 GB of HardDrive.

1)Boot From Windows cd ,MakeUpto Two Ntfs Partitions Say 20 Gb For C:/ and 20 Gb for D:/ and Rest Remains Free.

You can Make 1 Partition For Windows.

2)There is a Step Which is Included in The Dvd Installation of Ubuntu ,Which Will Show You The Other Operating Systems in The Partitions itself.

3)Now Install Ubuntu On The Free Partition .It Will Recoganize the Window Partition in Between Will Show the Partition Table Like Below (as per the Windows Installed):

Note :You Can Delete The Partition Which is Useless And Make Some Free Space For Linux.

Well I Personally Prefer the Custom Partitions in Linux,SO it is easy to understand all the Partitions.

Device                      Label          MountPoint         Type         Format         Size


/dev/sda1                                                                     ntfs                                     20003

/dev/sda2                                                             Extended                                 56306

/dev/sda5                                                                 ntfs                                        20003

Free                                                                     FreeSpace                                  39252

Now Above 20003 First Partition is Your Windows Partition(ntfs) and Other 20003 Partition is Your D:/ Partition(ntfs) and Now Click On Free and Make The Partition Like Below or As Per Your Required Space :

Device             Label         Mount Point             Type          Format             Size


/dev/sda1                                                                 ntfs                                     20003

/dev/sda2                                                             Extended                              56306

/dev/sda5                                                                 ntfs                                     20003

/dev/sda6                             /boot                         ext3                 yes             1028

/dev/sda7                             /swap                         ext3                 yes             1028

/dev/sda8                             /                                  ext3                  yes           20000

/dev/sda9                         /home                           ext3                 yes             17188

Freespace                                                                                                              8mb

Here at the Above Partition The Space I Have Allocated is :

/boot Partition is Of 1 Gb Nearly (You Can Give 512 Mb )

/swap Partition is Of 1 Gb Nearly(You Can Give 512 Mb)

/ is the Root Partition Holding All The Installed Softwares ,Files etc (You Can Give this space as Per Your Requirement Minimum of 9 Gb if You are Installing Both KDE And Gnome Enviroments)

/home is The Home Partition ,it is Holding Your Documents,Music Files etc (IT Should Be Large For Storing Documents And Music etc)

If Windows Operating is Not Showing Up at the Booting Screen.

Just Follow The Steps Below

Boot Into Ubuntu :-

Now Care fully Follow steps below:-


vi /boot/grub/menu.lst


gedit /boot/grub/menu.lst

At the end write this (if the lines below already exists skip the steps):-

title Windows XP
root (hd0,1)
chainloader +1

Now Save the file and Exit.

hd0 Refers To Your First Hard Drive and 1 Refers To Your Partition No. Where The Windows Installed(like sda1).

(hd0,1) can be Different as Per the Windows Installed.

Restart Your System Now You have the Options to switch to Windows and Ubuntu.


Happy Dual Booting.
